After the last wanshow I was a bit suprised with Linus. Normally he is pretty good at milking stuff. So could you at least use the stock buying to make some videos? For example:
Techquickie on how online stock trading works and which tools are best (for the avarage joe)
LTT video on custom hardware which is used by stock traders to keep latency to the stock market as low as possible (I hear some of these a very interesting)
LTT video on hardware/software you can use to keep track of market fluctuation and maybe something about machine learning algoritms used to buy stock etc, so simply said what would you need to start a hedgefund in terms of IT
It might soften the blow at least a little bit ;) .
